Premium airfield logistics solutions and cargo dolly platforms manufactured to strict aerospace operational specifications.
The global aviation framework is undergoing a historic shift toward ecological sustainability, smart diagnostics, and high operational reliability. Ground Operations (GSE) sit at the focal center of this movement. Aircraft Ground Power Units (GPUs) provide the crucial electrical interface that bridges the airport terminal electrical grid (or self-sustained energy cells) with the parked aircraft's primary avionics, climate, control systems, and engine starters.
Traditionally, parked aircraft relied heavily on onboard Auxiliary Power Units (APUs)—highly inefficient, kerosene-burning turbines that generate excessive carbon emissions, local air pollutants, and deafening noise levels on active ramps. By utilizing advanced 400Hz Solid-State Frequency Converters and specialized 28.5V DC rectifiers, airports can completely shut down APUs during turnarounds. This optimization decreases ground fuel burn, lowers regional greenhouse gas outputs, and extends engine component lifetimes.
Modern Ground Power Supplies represent more than simple transformers; they are complex grid-interactive power networks. As Tier-1 global suppliers and leading China factories, we integrate state-of-the-art solid-state systems, diesel-driven dynamic units, and lithium battery energy storage systems (ESS). This diverse product line ensures that commercial aircraft (such as Airbus A320/A350 and Boeing 737/787 platforms) receive continuous, transient-free electrical currents, shielding delicate onboard electronics from voltage spikes and frequency variations.
Exploring the convergence of solid-state topology, smart diagnostics, and localized battery storage systems in modern aviation ground power.
Moving away from rotary converters, our solid-state converters leverage IGBT (Insulated Gate Bipolar Transistor) technology. Double conversion circuits rectify the input 50Hz/60Hz grid power to smooth DC voltage before inverting it back into precise 400Hz power. This architecture minimizes harmonic distortion to less than 2%, reduces wear, and increases operational efficiency.
Zero-emission flightlines rely on containerized towable battery GPUs. Integrating clean LFP (Lithium Iron Phosphate) chemistry, these units deliver large reserve capacity for remote ramp parking. They are completely decoupled from active fuel logistics, run silently, and charge during off-peak periods, contributing directly to airport decarbonization.
Equipped with telemetry modules, modern GPUs monitor real-time cable drop compensation, insulation degradation, temperature anomalies, and voltage fluctuation profiles. Predictive maintenance systems alert fleet managers before faults occur, keeping operational ready rates above 99.8% across busy airfield hubs.

To reduce overall aircraft weight, aviation designers use high-speed generators running at 400Hz. This design allows transformers and electric motors to be smaller and lighter compared to 50Hz or 60Hz systems. Solid-state frequency converters take the input grid power (50Hz or 60Hz) and convert it to the precise 400Hz AC power required by onboard systems during turnarounds.
Our solid-state converters include multiple safety systems. These systems monitor for over-voltage, under-voltage, over-current, phase loss, reverse phase sequence, short circuits, internal high temperatures, and high cable drop compensation levels. If any parameter falls outside safe operating limits, the system cuts power instantly to protect the aircraft's avionics.
Commercial aircraft and widebody transport jets use 115V/200V AC power at 400Hz. In contrast, smaller regional commuter planes, business jets, and military helicopters rely on 28.5V DC power for their primary electrical systems and engine starters. We offer dual-output GPUs that provide both options from a single unit.
By replacing traditional diesel generators with battery-powered GPUs, airport operators can reduce fuel costs and lower overall maintenance needs. Battery systems eliminate engine maintenance, oil changes, and diesel fuel handling, while delivering quiet, zero-emission power that supports airport carbon-neutral targets.
All our ground power systems are designed, manufactured, and tested to meet international standards. These include DFS 400 (specifications for 400Hz aircraft power), ISO 6858 (aircraft ground support electrical requirements), Mil-Std-704 (aviation power characteristics), IATA AHM 910/921, and European CE standards.
